You're having work the 2.7 harder than you would a larger V8 or even the 3.5EB.
IMO I'd jump to the 3.5EB before going F250 diesel or 3/4 ton gas. @6600 lbs an F150 is plenty of truck. The 3.5EB won't need to work near as hard so you should gain 2-3 mpg's.
The F250 7.3 will suck more gas when not towing and is a lot more $$$ than an F150 3.5EB. If you plan on going to something bigger then yes the F250 is a better decision.
FWIW anything over 60 mph is going to really cut into anyone's mpg's.

I recently went from a '14 F150 with 3.5 EB to a '16 Ram 2500 CTD. Towing mpg went from 7-8 to 11-12 with the same camper (6.6K) and towing was much easier. Love the engine brake! Definitely use tow/haul, makes the entire experience better/safer, especially if you are in the mountains. But 250/2500 costs are an issue, so if towing flat and short, might stay with what you have, but if planning longer trips may want to upgrade.
Good Luck
Wow, you must have a heavy foot. I regularly get 10 mpg towing 7600 lbs @ 65 - 70 mph with my 2019 3.5 ecoboost and 10 spd transmission.
OP - you need to put that truck in tow/haul mode, that's why they have it, for towing! That transmission will be in the right gear all the time, you'll get a lot better tow, and better gas mileage also. That 10 spd transmission is a dream to tow with.
